BENJAMIN A. STEVENS, OF TOLEDO, OHIO.

APPARATUS FOR PLACING INSERTIONS lN RUBBER ARTICLES.

SPECIFICATION forming part of Letters Patent No. 710,817, dated October 7, 192. Application filed June 11,1902. Serial No. 111,118. (No model.)

To all whom it 77mg/ concern.-

Be it known that I, BENJAMIN A. STEVENS, a citizen of the United States, residing at Toledo, county of Lucas, State of Ohio, have in- Vented a certain new and useful Improvement in Apparatus for Placing Insertions in Rubber Articles; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to apparatus for placing insertions in rubber articles; and the object of my improvements is to provide means by which a strip or core may be readily inserted in an aperture formed in rubber.

In billiard-cushions and in some other articles made in whole or in part of rubber it is often desirable to form such articles with apertures in them and to insert more or less cable because of the adhesive nature of the material.

Referring to the accompanying drawings, Figure 1 is a side elevation 0f an apparatus embodying my invention. Fig. 2 is an elevation of the same on a larger scale and partly in section, part being broken away to economize room. Fig. 3 is a section on the line 3 3 of Fig. 1.

A is a section of rubber billiard-cushion, which is usually made in pieces nine (9) feet long.

a is a cylindrical aperture formed through the section A near the vedge against which the balls impinge when the cushion is upon the table.

Cisa bench or table-top supported upon legs D D. Y

l) b are standards upon the bench C.

c is a support upon the standard b l).

The billiard-cushion section A is laid upon the support c and is supported thereby.

e e are standards rising from the bench C and supporting clamps E E, by which the ends of the section A are fastened.

F is a tube supported on standardsff upon the bench C in line with the aperture a in the ture a.

section A. One end of the tube F is reduced in size, forming the conical extension F2.

F is a plug by which the unreduced end of the tube F may be opened or closed.

z' is a piece of rubber hose communicating with the interior of the tube F.

I is an air-pump adapted to force air through the hose 'i into the tube F. The tube F is a little longer than the section A.

G is a second tube secured at the upper end of a standard g, rising from the bench C. The

tube G has a conical end G2 entirely similar to F2.

G' is a gland or stuffing-box adapted to close the nnreduced end of the tube G. Said tube is located in line with the aperture a and at the opposite end of the section A to that at which the tube F is located.

.l is the core or insertion to be placed in the aperture d.

H is a Wire passing through the stuflingbox G and tube G and provided at its end with the handle H. The wire H may be made of sufficient length to pass through the section A and tube F.

The method of adjusting the abovedescribed apparatus and its operation are as follows: The section Ais laid upon the support c and its end secured by clamps E by means of the thumb-screws E2. The end of the wire H is secured to one end of the core J, and the core is drawn into the tube F by means of said Wire', and the end of said tube is closed by the plug F. The tubes F and G are then forced toward eachother, forcing their conical ends tightly into the ends of the aper- Air is'then forced into the tube F, and consequently into the aperture d, by means of the pump I until it has reached a pressureof perhaps sixty pounds. This eX- pands the aperture a, and the core J may be then drawn freely into it by drawing upon the wire H by means of the handle H/ or otherwise. The core is drawn through until both ends protrude from the ends of the aperture. The tubes F and G are then withdrawn, when the material ot' the section A contracts and embraces the core tightly.
